integration-test - shows how WITH DOCKER and docker-compose can be used to start up services and then run an integration test suite.
monorepo - shows how multiple sub-projects can be co-located in a single repository and how the build can be fragmented across these.
multirepo - shows how artifacts from multiple repositories can be referenced in a single build. See also the grpc example for a more extensive use-case.
Examples by Earthly features
import - shows how to use the IMPORT command to alias project references.
cutoff-optimization - shows that if an intermediate artifact does not change, then the rest of the build will use the cache, even if the source has changed.
multiplatform - shows how Earthly can execute builds and create images for multiple platforms, using QEMU emulation.
multiplatform-cross-compile - shows has through the use of cross-compilation, you can create images for multiple platforms, without using QEMU emulation.
Examples by use of other technologies
grpc - shows how to use Earthly to compile a protobuf grpc definition into protobuf code for both a Go-based server, and a python-based client, in a multirepo setup.
terraform - shows how Terraform could be used from Earthly.
tests - a suite of tests Earthly uses to ensure that its features are working correctly.
Earthly's own build
As a distinct example of a complete build, you can take a look at Earthly's own build. Earthly builds itself, and the build files are available on GitHub:
